Abstract
Inventia se refera la un procedeu continuu de obtinere a polietilentereftalatului pigmentat în masa, destinat filarii directe pentru realizarea de fibre textile, constând în transesterificare, policondensare, pigmentare polimer, operatia de pigmentare a polimerului realizându-se prin dispersarea a 8...15% pigmenti sau coloranti de dispersie în etilenglicol, încalzire la 120...170 degree C si amestecarea cu polimer incolor în proportie de 2...5% la un vid de 250...300 torri.
